Well, Dennis, you have obviously had a very bad experience and I'm sorry to hear that.
For reasons that I won't bore people with, I ended up several years ago with cash, but no investments. And falling interest rates. In desperation, I consulted a UK financial adviser and, following his advice, had an acceptable income and increasing capital. The crash of 2007 knocked me back, but I continued to draw down income on what became a fairly static amount of capital.
About four years ago, with volatile exchange rates and a firm decision to make my base in NZ, I shifted most of my capital across to NZ (while the dollar was at a record high against the pound!) I went to another financial adviser, who works for an outfit here in NZ, which appeared to be very transparent. They are sufficiently small that my adviser recognises who I am and remembers details of our conversations, but sufficiently large that they can, apparently, employ good people. In spite of the wild fluctuations that can occur, in the intervening years, I have drawn a steady income and watched my capital grow. Had I put the money in term deposit, it would be a lot less, because the interest rates offered are not sufficient to give me the income I wanted.
Unfortunately, it does all depend on the investment company you are dealing with: some appear to be very straightforward (apparently the head of my company starts and ends every meeting by saying to the staff: "Remember - don't lose the bloody money!"), some appear to be complete charlatans. I should talk to friends and acquaintance and see if anyone has long-term good experiences with a company, if possible.
It's all a gamble and there is always good and bad luck - just like being runover by a car. But you can try and stack the odds in your favour by doing your homework carefully.
